O. T. JUDKINS, OF BOSTON, MASSACHUSETTS.

GAS-REGULATOR.

Specification of Letters Patent No. 34,507, dated February 25, 1862.

To all whom t may concern.'

Be it known that I, CHARLES Tro'r JUD- KiNs, of Boston, in the county of Suffolk and State of Massachusetts, residing in London, England, have invented certain new and useful Improvements called An Improved Gas-Regulator, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which is represented a plan of the regulator.

This invention has for its object improvements in apparatus for regulating or governing the supply of gas to burners. For this purpose the gas is introduced by a supply pipe into one chamber or compartment of the regulator, denominated an inlet chamber; from this chamber or compartment the gas passes into a second chamber or compartment; but the amount of gas passed or passing from one chamber to the other is regulated by means of a valve which is ,caused to close or open a passage between the two compartments, more or less as circumstances may require. In these particulars my improved regulator does not differ materially from other gas regulators. The valve regulating the passage of the gas between the inlet and outlet chamber or compartment of the regulator, is carried by a cover, which may be made of cast iron, and similar to others in use, having turned down edges, which enter a trough containing Quicksilver or other uid (by preference quicksilver). This cover moves upon centers e, c, as shown in Figure 3 inthe accompanying drawings, so that the opposite end of the cover rises and falls so as to close the aperture (a) Fig. 2, and is constructed with an area very much larger than that of the valve, by which means the varying pressure of the gas causes the valve to rise or fall as may be required, so as to give at all times one uniform pressure in the outlet chamber, as well as at the burners.

Such being the nature of my invention, the following is the manner in which the same may be performed, as will be seen by reference to the accompanying drawings.

Fig. 1 is the cover or disk of the regulator, having turned down edges which rest in a trough containing fluid. Fig. 2 is a longitudinal section of the regulator. Fig. 3 is the top view of the regulator showing the lever, the fulcrum rod and the weight. Figs. 4 and 5 are transverse sections of the regulator showing the two ends of the same. Fig. 6 is the plan view of the bottom of the regulator. Fig. 7 shows the form of the turned down sides 0r edges of the cover.

Similar letters of reference indicate corresponding parts in the several figures.

C, I denominate an inlet or high-pressure chamber. D an outlet or low-pressure chamber communicating with C by means of the aperture (c) g E is a cover with turned down edges (d, d); F represents a trough or passages containing quicksilver or other fluid into which the edges (el, el) sink sufliciently to form a gas tight joint.

I-I is a valve attached to the cover by means of the spindle I and two small nuts (hl, L,) or in any other convenient way; K is the top or cover of regulator; L is a movable weight placed upon the lever O, and confined if necessary at any convenient point for balancing the same, which lever rests upon the fulcrum (Z) and is connected with the cover E by means of the pin P so as to open or close the valve to admit any desired pressure in the outlet chamber.

The action of the regulator is as follows: The gas being admitted from the main by any convenient inlet M passes by the valve H through the aperture (a) to the outlet chamber D, the pressure in that chamber being regulated by the adjustment of the weight L' as iswell understood; the gas passes from the chamber D through the outlet N to the burners, the cover E rising or falling according to the pressure.

Having now described the nature of my invention, and in what manner the same is to be performed, I wish it to be understood that I do not claim as of my invention, the eX- clusive use of the several parts of this regulator when taken separately, such or similar parts having been in use in other gas regulators; but

What I claim is- The combination and arrangement of the valve H, with the pivoted or hinged cover E, the lever O, and adjustable balance weight L, substantially as and for the purpose and objects herein set forth.
